Possible errors in carbon dating 8 rules for dating a single mom
As samples get older, errors are magnified, and assumptions can render carbon dating all but useless.For example, variations in greenhouse effects and solar radiation change how much carbon-14 a living organism is exposed to, which drastically changes the “starting point” from which a radiocarbon dating test is based.
For this reason, it’s preferable to date objects using multiple methods, rather than relying on one single test.
Likewise, different living things absorb or reject carbon-14 at different rates.
Two plants that died at the same moment, but which naturally contained different levels of radiocarbon, could be dated to drastically different times.
In short, carbon dating is as useful as any other technique, so long as it’s done properly and the results are objectively interpreted.
It is not, however, an inherently error-free or black-and-white method for dating objects.
